reusable templates

I am looking at NiFi and StreamSets and really enjoying the ease of use of SDC. One feature I am missing to find in UI or docs is reusable templates which is one of the core features of NiFi. The idea is to create a reusable processes aka black boxes with predefined inputs and outputs.

In my case, I need to design 200 pipelines which are very similar. With NiFi, I could create a template and then reuse it.
More importantly, if I need to make changes, I only need to change the template and that change will be applied to all the pipelines based on that template.
